Dynamical Analysis of a Delayed Diffusive Predator–Prey Model with Additional Food Provided and Anti-Predator Behavior

open access: yesMathematics, 2022
We studied a delayed predator–prey model with diffusion and anti-predator behavior. Assume that additional food is provided for predator population. Then the stability of the positive equilibrium is considered.

Flow‐Dependent Inertial Permeability Defines Crossover Between Darcy and Forchheimer Flow Regimes

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We present mechanistic evidence that the Forchheimer inertial permeability coefficient (β $\beta $) is flow‐dependent in the weak‐to‐intermediate inertia crossover regime, governed by pore‐scale eddy growth‐to‐confinement dynamics. In contrast to classical theory, β $\beta $ attains steady‐state (βs ${\beta }_{s}$) asymptotically in the ...

Global existence of periodic solutions in a simplified four-neuron BAM neural network model with multiple delays

open access: yesDiscrete Dynamics in Nature and Society, 2006
We consider a simplified bidirectional associated memory (BAM) neural network model with four neurons and multiple time delays. The global existence of periodic solutions bifurcating from Hopf bifurcations is investigated by applying the global Hopf ...

TVB C++: A Fast and Flexible Back‐End for The Virtual Brain

open access: yesAdvanced Science, Volume 13, Issue 2, 9 January 2026.
TVB C++ is a streamlined and fast C++ Back‐End for The Virtual Brain (TVB), designed to make it as flexible as TVB, and FAST. Another pillar is to be fully compatible with TVB so easy bindings can be created from Python. Users can easily configure TVB C++ to execute the same code but with enhanced performance and parallelism.

On qualitative analysis of an ecological dynamics with time delay

open access: yesAsian Journal of Control, Volume 28, Issue 1, Page 46-56, January 2026.
Abstract In this paper, we study a fractional‐order predator–prey system with time delay, where the dynamics are logistic with prey population commensurate to the carrying capacity. Mainly, by linearizing the system around the equilibrium point, we first analyze the stability and then prove the existence of Hopf bifurcation.

Hopf bifurcation analysis of Sel’kov model with time delay

open access: yesXi'an Gongcheng Daxue xuebao, 2023
The Sel’kov model with time-delay diffusion under homogeneous Neumann boundary conditions is considered. Firstly, the local asymptotically stability of the positive equilibrium point of the model is obtained by using spectral theory.
